Angle threaded shut-off valve Comap 428714C nickel-plated, adjustable flow control 1/2–3/4"

Angle threaded shut-off valve Comap 428714C nickel-plated with adjustable flow control for 1/2–3/4" threaded connections is designed for use in plumbing and heating systems where precise flow regulation and reliable isolation are required. The nickel-plated finish offers corrosion resistance and a smooth surface for easy handling during installation and maintenance. The valve integrates a shut-off function with an adjustable flow control mechanism, enabling both full isolation and fine adjustment of flow rate in compact installations such as radiators, manifolds and branch lines.

Advantages

The nickel-plated surface increases durability and resists corrosion in typical domestic and commercial environments. The angle design saves space and simplifies connection to radiators and piping runs. Adjustable flow control provides the ability to set a specific flow rate for balancing or commissioning tasks, while the shut-off capability allows quick isolation for servicing without draining large sections of the system.

Suitable for

• Radiator connection and isolation in domestic heating systems
• Balancing and commissioning of pipework and manifolds
• Branch lines and compact installations where space is limited
• Replacement or upgrade of existing threaded valves in residential and commercial buildings

Key specifications

• Configuration: angle (90°) shut-off valve with integrated flow control
• Connection type: threaded connection compatible with 1/2–3/4" fittings
• Finish: nickel-plated surface for enhanced corrosion resistance
• Functionality: adjustable flow regulation plus full shut-off
• Typical applications: radiator valves, manifold branches, pipework balancing

How to use

Install the valve into the threaded connection point of the radiator, manifold or pipework following standard plumbing practices and local codes. Use appropriate sealing material on threads as required and tighten to a torque suitable for threaded fittings of the specified size. Set the valve to fully open to flush the system, then adjust the flow control to the required position for balancing. For isolation, turn the valve to the closed position to stop flow to the downstream section before servicing.

Usage recommendations

During installation and maintenance, ensure compatibility with the system medium and operating temperatures. Inspect sealing surfaces and threads for damage before fitting, and perform leak tests after installation. For long-term reliability, avoid excessive overtightening and consider periodic checks during routine system maintenance.
